Explosion Hazards in Baghouses and Dust Collectors

Transport of sparks through ducts. ...This spark and the hot gas associated with the spark can travel hundreds of feet in a duct... Spark suppressors are placed in the duct to change the laminar flow to turbulent (coarse) flow. This agitation or turbulence strips the air from around the ember and cools the spark below ignition temperature.

Gary Berwick, P. Eng. at Quality Air Management shares with readers his informative article, "Explosions and Fires; Baghouses, Cartridge Dust Collectors." Fascinating video on the QUENCHER™ in-line spark arrester device for spark Cooling and air blending for dust collection systems.
